Steps and preparation

  • The competitive sequence is solution brief, invited pitch, then invited proposal. Invitations do not promise award funding.

Research scope and sources checked

The first program-depth pass checked the cited program pages, notices and legal framework. Evidence is limited to the named routes and source-access notes; it does not establish every implementation of the statute.

What remains unverified

  • No open DIU CSO was displayed on the checked date; project-specific eligibility, security restrictions, appropriation and pricing remain unresolved until a solicitation is selected.

A dated source check is not continuing monitoring. Recheck the linked official notice before preparing a submission. Browse program research →

Confidence: High on express authority and cited conditions; execution assignment is illustrative unless statute expressly names it.

Currentness: GovInfo 2024 Code (includes FY2025 NDAA, P.L. 118-159) read in full for cited provision; targeted FY2026 NDAA P.L. 119-60 amendment/repeal sweep.

OLRC indexed current text dated 2026-09-15 cross-checked for key thresholds and eligibility.
